DOOR-LATCH.

Be it known that L'ELMER H. Tonr, a citizen of the United States, residing at Morrisonville, in the county of Christian and State of Illinois, have invented certain new and useful Improvements in Door-Latches, of which the following is aspecification.

' This invention relates to latches for swinging doors, such as are desirable in connection withordinary barn doors, or the like.

The invention comprises certain specific details of construction which will be fully set I forth and claimed hereinafter, and illustrated in the accompanying drawings, in which- Figure 1 is a vertical face view of a door provided withthe attachment, the door being held open; Fig. 2 is a similar view, the

, door being closed and viewed upon the opposite side from that of Fig. 1; Fig. 3 is an enlargedcross section through the door and I supporting means substantially on the line 3 3 of Fig. 1, the latch mechanism being in plan, ,andFig. 1 is a view on a still larger scale, the parts being in the same position as indicated in Fig. 2. i

Throughout the following detail description and on the several figures of the drawings similar parts are referred to by like reference characters.

As a convenient embodiment of the invention there is indicated 111 any conventional manner at 10 a swinging door hinged to a door frame 11, and adapted to be held securely either in a closedor an open position.

Secured to the door frame 11 is a keeper 12 'havinga hole or notch 12 and a flaring outer end lS: At any suitable support, such as an extension of the building or a post indicated at 14, s connected in any convenient manner a second keeper 15 having a hole or notch 15 i and a flaring outer end16; The keepers 12 and 15 will bearranged at substantially the same distance from the axis of the door hinges 17.. I

The door latch is double acting, and com prises a double-L structure 18, located in a notchor recess 19 formed in the outer edge of the door and pivoted on a stationary. support, shown in the form of a staple 20 secured in the door at the bottomof said recess 19, so as to swing in a' plane transverse to the plane of Specification of Letters Patent.

the door. The nose 18 of the catch extends outwardly in a direction parallel with the general plane of the door and is adapted to cooperate with either of the flared portions of the respective latches and to enter the hole adjacent thereto for holding the door in the position to which it is being moved at that time. I prefer to employ in connection with the latch a spring to insure the engagement of the nose 18 with the keepers. Such spring is shown as being of the coiled species at 21 and is mounted within and projects through a hole 22 through the door adjacent to the re cess 19. One end of the spring is anchored to a washer 23 on one side of the door, and the other end of the spring is secured to the latch in a hole 24 from the opposite side of the door. The normal tendency of the spring, therefore, is to maintain the nose of the latch in engagement with one or the other of the keepers, or in such a position with respect to the do or as to insure its engagement with the keepers when the door is swung to either eX- The nose 18 may be with drawn from the keepers by any suitable means. I have shown, however, for this purpose a pull-piece 25 connected to one end of the latch for manipulation thereof on one side of the door, and a pull-piece 26 connected to the other end of the latch adjacent to the nose 18 for manipulation of the latch'on the opposite side of the door. The pull pieces 25 and 26, being pivoted to the latch, may occupy any convenient angle with respect thereto.

Having thus described the invention, what is claimed as new is:

1. The combination with a door irame and a door pivoted thereto, of a pair of keepers, a latch of double-l... form pivoted transversely of the door and extending upon opposite sides thereof, the latch having a nose for cooperation with either of said keepers, means to cause the latch to swing on its pivot and maintain it in engagement with either keeper,

and means connected to the opposite ends of the latch whereby the same may be operated from either side of the door.

2. The combination with a door frame and a door pivoted therein, of a pair of keepers, a door latch of double-l... form located in a recess in the edge of the door and pivoted I be operated from either side of the door, suh- 10 therein to swing in a plane transverse to the stantially as set forth.
